Just incredible that I am learning this for free! Even if I do not fully understand all the details, just grasping the concept is a game changer. Thanks! 🙏
I got burnt trying to short SITM thinking there was no way their data center bull case would play out because it was significantly worse (and more expensive) than quartz. I never understood why NVDA started using them until now, thanks
Yea it took me a week to figure out why Nvidia picked SiTime for NVLink. I literally work in industry and it took me a while lol. PPM control realization mind blowing for me.
came here from your latest masterpiece (optical communication systems). even tho this is a year old i learned so much more than anywhere and anyone else. really appreciate your work. thank you
Thanks for the article. I have 0 technical background but what I’ve learned from finance gig, CPO supply chain should look a lot like SiPh's. Could SOI (silicon-on-insulator) and even InP (indium phosphide epi) providers become hidden gems in the CPO race? If not mistaken, most SiPh uses SOI (Soitec), and Intel specifically uses large areas of InP epi stacked on top for photonic elements (from VPEC, IQE, and mostly Landmark Opto) for their pluggable SiPh to replace various discrete components. Compound on Si from Aeluma definitely interesting, but they’ve chosen to start with PD, which is quite interesting, likely lower barriers of entry.
Testing providers like Chroma and Aehr will likely do really well too?
The biggest losers are probably the discrete optical component companies?
Sir , you bring me joy with your writing. Well done explained , deep technical stuff that is translated into perspectives for investing in key semiconductor areas . You are also funny and so generous. Really appreciate your work . Kudos. I’m at feisal@substack
Yup, I’m subscribed with AYZ and his ANET thesis saves me from shorting it. Other than that, amazing write ups. You can be a professor at this rate.

Thank you so much for this well researched article. This is a must read

typo at the start of [2]Noise "signal no noise ratio"
fixed
